The $\alpha +d\to {}^6\mathrm{Li}+\gamma$ astrophysical $S$-factor and its implications for Big Bang Nucleosynthesis

A. Grassi, G. Mangano, L. E. Marcucci +1

The $\alpha +d\to {}^6\mathrm{Li}+\gamma$ radiative capture is studied in order to predict the ${}^6$Li primordial abundance. Within a two-body framework, the $\alpha$ particle and the deuteron…
